If you had lots of money, what unnecessary thing would you splurge on?

That depends on what you consider unnecessary...

For me, I would splurge on fine dining. I'd find two or three places where the cuisine is worth the high prices, then I would go to those places every so often. I can't think of anything else I'd spend $$ on unless I absolutely had to.

I would go to Aruba and bring all my family and friends along and have a grand old time!
